To see how this works we the printing style to normal, to start with. The following do this.

<ESC > “ + ” ... (codes you include)

... CHR%(30)

<ESC > “ + ” CHR$( 1)

can build a macro that will reset no matter what style it may be program will define a macro to

10	LPRINT CHR$(27);“+“;	‘Start macro
20	LPRINT CHR$(27);“h”;CHR$(O); ‘Big character off
30	LPRINT CHR$(~~);“!“;CHR$(O); ‘Select normal pica
40	LPRINT CHR$(27);“T”;	‘Super & subscripts
	off
50	LPRINT CHR$(27);“a”;CHR$(O); ‘Left-aligned
	printing
60	LPRINT CHR$(30)	‘End macro
	definition

As the comments in the program show, we started to define 1the macro in line 10. Line 20 cancels big character printing.

Line 30 sets normal pica, and this command also cancels proportional pitch, condensed print, expanded print, boldface, emphasized, italics, and underlining. Line 40 cancels super- scripts and subscripts. Line 50 sets left-aligned printing. Then, line 60 ends the macro definition. This printer will remember this macro until the power is turned off or until a new macro is defined. A macro can hold up to 16 bytes (characters) of information. The one that we defined contains eleven.

Now that you have defined a macro, let’s see how to use it. This program will print one line using several printing features. Then it “calls” the macro in line 60. When line 70 prints the style is “plain vanilla” because the macro has reset it.
